Another reason may be if you are explicitly calling an external library or API with a C-style interface. Setting up a callback in such cases often means context data must be supplied and returned in the callback, and such an interface usually provides only a 'simple' void* or int*. Allocating an object or struct with new is appropriate for such actions, (you can delete it later in the callback, should you need to).
